PERFORATING-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 583,616, dated June 1, 1897.

Application filed January 24, 1896. Serial No. 576,738. (No model.)

To all whom, it may concern,.-

Beit known that I, CORTLAND CARLTON, of Kansas Oity, in the county of Jackson and State of Missouri, have invented a new and Improved Perforating-Machine, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in machines for perforating paper and the like, and has for its object to provide a device of this character of a simple and inexpensive construction which shall be adapted to perforate the paper in a uniform manner and which shall be adapted for rapid operation and for adjustment so as to perforate the paper along different lines.

The invention consists in such combinations and features of construction as are de lined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side view of a machine constructed in accordance with my invention, portions thereof being'broken out in order to illustrate certain of the operating parts. Fig. 2 is a vertical section taken through the machine in the plane indicated by the line x rc in Fig. 1. Fig. 3 is an enlarged sectional detail view on the line y y in Fig. 1, showing the construction of the cylinder of the machine; and Fig. 4 is a similar view on the line z z in Fig. 1, showing the construction of the perforating-disk.

In the views, 1 indicates the frame, constructed, preferably, of metal, at the upper part of which are journaled parallel shafts 2 and 3, provided with driving devices, (not shown,) said shafts being preferably made tubular, as shown in Fig. 1. On the shaft 2 is mounted a cylinder 4, said cylinder being made in the form of an ordinary pulley or drum and having one side recessed, as indicated at 5 in Figs. 1 and 2.

The cylinder 4 is grooved around its periphery, as indicated at 6, and in said groove is arranged a band or strip 7, of lead or other soft material, adapted to underlie the paper at the point where the same is engaged by the perforating device, as hereinafter explained, and said band or strip 7 has its end portions 8 bent downalong the sides of the recessed portions 5 of the cylinder, as clearly shown in Fig. 1, and secured to said sides by means of screws or the like, as will be readily understood.

The perforating device comprises a disk 9, having a toothed or serrated edge, as clearly shown in the drawings, said disk being mounted on a collar 10, secured on the shaft 3 of the machine in such a position that the edge of the disk 9 is adapted to engage the paper on the cylinder 4, as will be hereinafter explained, at a point opposite the strip 7 on said cylinder, and said collar 10 is provided with a reduced screw-threaded portion 11, adapted to receive a nut 12, whereby the disk 9 is held in place on the collar, as clearly shown in the detail view Fig. 4.

The machine is provided with a sheetfeeding table 13, from which are fed sheets of paper or the like to be perforated, and with a delivery-slide 14 for the discharge of the sheets and with a paper-rack 14a beneath said delivery-slide and adapted to receive the sheets passing over the same in a wellknown Way, and the sheets a are fed from the feed-table 13 by means of a grip moving in unison with the cylinder 4 and of the construction I will now describe.

The gripper is mounted on a frame 15, eX- tending transversely of the machine parallel to the shaft 2, said frame being provided with arms 16, having bossesV at their ends, which are secured to the opposite end portions of said shaft 2, as clearly shown in Fig. 2, and one jaw 17 of the gripper is formed integrally with the frame 15, as clearly shown in Fig. 1. The frame 15 may be adjusted circumferentially on the shaft 2 and within the recessed or cut-away portion 5 of the cylinder 4. A shaft 18 extends longitudinally of the frame 15 of the gripper, being j ournaled in brackets or lugs 19 at opposite ends thereof, and on said shaft is secured a movable gripper-jaw 20, arranged to grip the paper between it and the stationary jaw 17, as will be readily understood. The shaft 1S is provided with a spring 21, arranged to hold the movable jaw 2O normally in engagement with the stationary jaw 17.

One end of the shaft 18 projects beyond the frame 15 and is provided with a crank- IOO arm 22, the outer end of which is coupled to a link 23, extending downward and connecting at its lower end by means of a ball-joint or universal couple 24 with the outer end of an elbow-lever 25, pivoted at 27 on the frame 15 and arranged to play in a guide 2G, the opposite end of said lever being coupled, as indicated at 2S in Fig. 2, with the inner end of a slide-bar 20, mounted to slide in the guide 2G and having its outer end forked to receive a roller 30, pivoted between said forks.

The roller 30 is arranged to project beyond the frame 15 and the other devices carried thereon and is in engagement with a disk 31, mounted to slide longitudinally on the shaft of the said disk, being provided at its lower part with a socket 32, in which is held, by means of a set-screw 33, the upper end of an e1bow-lever34, pivoted at 35 to a brace 36 of the frame 1 of the machine, as clearly shown in Fig. 2, and having a horizontal arni provided with a roller 37, engaged by a cam 38 on a shaft 39, journaled at one end in a bearing 40 on said brace 36 and having its opposite end journaled, as shown at 41 in Fig. 2, in the side of the frame 1.

As shown in the drawings, the cam 3S is approximately a half-circumference in length and suitably located upon the shaft, so that it will actuate the cooperating parts, as described.

On the shaft 39 is iixed a large gear-wheel 42, meshing with a pinion 43 on the shaft 2, and by preference the gear-wheel 42 is provided with twice as many teeth as the pinion 43, whereby it will be seen that the shaft 39 will be turned one complete rotation at cach two rotations of the shaft 2.

In operation the shafts 2 and 3 being driven in any suitable way, as by means of pulleys and belts, the cylinder 4 is caused to revolve together with the gripper-frame 15, which, as will be readily understood from Figs. 1 and 2, is adjust-ably mounted on the shaft 2, so as to be set in any preferred position relatively to the cylinder 4. The gripper will be usually mounted, as seen in Fig. 1, at the cut-out portion 5 of the cylinder. As the cylinder and gripper-frame turn, the shaft 39 is rotated so as to move the disk 3l endwise on the shaft 2, whereby the gripper-jaw 20 is moved out of engagement with the gripper-jaw 17 to permit the insertion of a sheet a of paper, as indicated in Fig. 1, between said jaws. When the cam 3S ceases to act on the roller 37, the spring 21 returns the movable gripper-j aw 20 into engagement with the gripper-jaw 17 to securely hold the sheet of paper, and said sheet will thereupon be drawn down over the feed-table 13 and will be carried around, its rear part passing upon the periphery of the cylinder 4 and being perforated by the disk 9, which will engage said sheet at a point opposite the leaden strip 7. When the cylinder and gripper shall have completed one rotation, the cam 38 will again act upon the roller 37, so as to open the gripper-jaws and permit the sheet of paper carried thereby to pass down the delivery-slide 14 and onto the rack 14, after which the cylinder and gripper will complete another rotation, this, however, being accomplished without perforating the sheet, since the gripper will have passed the point at which it grips the paper without having been supplied with a fresh sheet.

By adjusting ihe gripper-frame on the recessed or cut-away portion 5 ot' the cylinder 4 the distance between the paper end which is gripped and the point at which the perforating begins may be regulated. This enables me to control the length of the stub or unperforated portion of the work.

The shafts 2 and 3 will be, by preference, made of such a length and the other parts of the machine will be so proportioned that, if desired, a series of cylinders and perforatingdisks may be arranged on said shafts, as indicated at l) b in Fig. 2, whereby it will be seen that several sheets of paper may be perforated at once or that a wide sheet may be perforated along different lines.

From the above description of the invention it will be seen that the device is of an extremely simple and inexpensive nature and is well adapted for the purposes for which it is designed, and it will also be obvious that the invention is susceptible of considerable modification without material departure from its principles and spirit, and for this reason I do not wish to be understood as limiting myself to the exact form and arrangement of the parts herein set forth.
